Abstract: The Internet, social networks, power grids, gene regulatory networks, neuronal systems, food webs, social systems, and networks emanating from augmented and virtual reality platforms are all examples of complex networks. Collection and analysis of data from these networks is essential for their understanding. Traffic traces collected from various deployed communication networks and the Internet have been used to characterize and model network traffic, analyze network topologies, and classify network anomalies. Data mining and statistical analysis of network data have been employed to determine traffic loads, analyze patterns of users' behavior, and predict future network traffic while spectral graph theory has been applied to analyze network topologies and capture historical trends in their development. Machine learning techniques have proved valuable for predicting anomalous traffic behavior and for classifying anomalies and intrusions in communication networks. Applications of these tools help understand the underlying mechanisms that affect behavior, performance, and security of computer networks.

Artificial Intelligence revived in the last decade. The need for progress, the growing processing capacity and the low cost of the Cloud have facilitated the development of new, powerful algorithms. The efficiency of these algorithms in Big Data processing, Deep Learning and Convolutional Networks is transforming the way we work and is opening new horizons. Thanks to them, we can now analyse data and obtain unimaginable solutions to today’s problems. Nevertheless, our success is not entirely based on algorithms, it also comes from our ability to follow our “gut” when choosing the best combination of algorithms for an intelligent artefact. It's about approaching engineering with a lot of knowledge and tact. This involves the use of both connectionist and symbolic systems, and of having a full understanding of the algorithms used. Moreover, to address today’s problems we must work with both historical and real-time data. We must fully comprehend the problem, its time evolution, as well as the relevance and implications of each piece of data, etc.It is also important to consider development time, costs and the ability to create systems that will interact with their environment, will connect with the objects that surround them and will manage the data they obtain in a reliable manner.
In this keynote, the evolution of intelligent computer systems will be examined. The need for human capital will be emphasised, as well as the need to follow one’s “gut instinct” in problem-solving. We will look at the benefits of combining information and knowledge to solve complex problems and will examine how knowledge engineering facilitates the integration of different algorithms. Furthermore, we will analyse the importance of complementary technologies such as IoT and Blockchain in the development of intelligent systems.It will be shown how tools like "Deep Intelligence" make it possible to create computer systems efficiently and effectively."Smart" infrastructures need to incorporate all added-value resources so they can offer useful services to the society, while reducing costs, ensuring reliability and improving the quality of life of the citizens. The combination of AI with IoT and with blockchain offers a world of possibilities and opportunities. The use of edge platforms or fog computing helps increase efficiency, reduce network latency, improve security and bring intelligence to the edge of the network;close to the sensors, users and to the medium used.
This keynote will present success stories regarding biotechnology, smart cities, industry 4.0, the economy, and others. All these fields require the development of interactive, reliable and secure systems which we are capable of building thanks to current advances.Several use cases of intelligent systems will be presented and it will be the different processes have been optimized by means of tools that facilitate decision-making.

Abstract: This keynote focuses on both AI for cybersecurity and cybersecurity for AI for emerging systems and applications. Lately, ML algorithms and AI systems have been shown to be able to create machine cognition comparable to or even better than human cognition for some applications. Machine learning algorithms are now regarded as very useful cybersecurity solutions for different emerging applications. However, because ML algorithms and AI systems can be controlled, dodged, biased, and misled through flawed learning models and input data, they need robust security features and trustworthy AI. It is very important to design and evaluate/test ML algorithms and AI systems that produce reliable, robust, trustworthy, explainable and fair/unbiased outcomes to make them acceptable by diverse users. The keynote covers applications and use cases of secure and trustworthy ML/AI and their success and pitfalls.

Abstract: Modern handheld devices and systems are developed day by day, in order to satisfy the complexity of users’ needs and applications. Nowadays, integrated circuits (ICs) play a sensitive role in devices’ operation, since they are the main cores for almost each type of process and data transaction. The needs for high performance, minimized area, and less power, are more demanding each time, and electronic design automation (EDA), is oriented as a crucial factor, for these targets. Although, besides the traditional circuits and systems, design approaches, the arising threats in hardware each time, make very important the priority for secure hardware design, and trusted devices, at the same time. Traditional approaches of design and test, are argued, since most of the processes’ parts, need considerations, assumptions and specifications, for both trustworthy and security in all metrics, including modeling and evaluation. This keynote talk, gives a detailed overview of hardware security and EDA approaches, including security threats, in integrated circuits, though the design cycle. It also, deals with, the countermeasures and the motivation of the prior art. Examples of modern applications are introduced, in sense of trusted hardware, and secure by design. Solutions, and alternative approaches are figured out, as well, detailed overview is discussed, for the expectations of future, for both users’ applications, and devices.
